Abstract
A process for making a model skin surface for testing adhesion of medical adhesive as a screening test and/or as an alternative to costly and highly variable human skin substrates including casting silicone rubber on human skin to produce a mold having human skin topography and pouring a water-swellable, water-soluble proteinaceous material along with a crosslinking agent and fatty acid constituent into the mold. The proteinaceous material crosslinks while in the mold and the water content of the material is adjustable to simulate varying moisture contents in human skin.
